Mr Windsor was one of a number of MPs to talk to Mr Slipper before he gave up the role in October, in the wake of the public release of a lewd text message exchange between the parliamentary speaker and staffer James Ashby.

The Federal Court today threw out Mr Ashby's sexual harassment case, ruling that the former staffer had brought the case "for the predominant purpose of causing political damage to Mr Slipper''.

Mr Windsor told AAP the issue of the speaker's job should not be revisited.

"I think the speakership is a separate issue to guilt or innocence in a court,'' he said.

"I don't have an issue with that decision. It was the best thing for Peter Slipper, for his family and the parliament and for the nation for him to step aside ... and he would probably agree with that.''

Mr Windsor said that any detailed commentary should wait until Mr Ashby completed his court appeal.

However Mr Windsor said it was clear that the federal opposition had "got some political advantage'' from the case.

"That's been their strategy - to use it to damage the government,'' he said.

"If Ashby's appeal isn't successful the community will make its own judgments ... as to the politics of it.''

Mr Windsor said he had been barraged with "vitriolic stuff'' from the public while he stood by Mr Slipper's right to due process.
